SELF-ADJUSTING DOOR/LOCK.

Application filed August 16, 1924. Serial No. 732,553.

This invention relates to new and useful block and an opening 11 therethrough improvements in door locks and more through which the head 12 of the latch me1nparticularly to that type known as the slidber operates, the same being thrown foring latch lock. The main object of my inwardly to a retaining position by means of a 5 vention is the provision of a lock of the spring member 13 arranged within the sliding bolt type wherein the bolt is formed body 1. v to provide for transverse movement of the The plate 7 is provided with the usual lock same as well as longitudinal movement bolt opening 1-1 and in the present instance whereby the same may ride upon an inthe opening 15 through which the latch 05 1o clined surface on the locking plate and be operates is disposed at an oblique angle with positioned within the usual opening formed respect to the position of the plate 7 as in thelocking plate behind a shoulder which clearly illustrated in Fig. 2 and this openis beneath the inclined portion so as to posiing is longer than the length of the latch ively prevent the bolt from becoming dishead 12 to permit movement of the latch 15 engaged from the locking plate unless manuhead in the opening 15 so that the same may ally manipulated. raise and lower as setforth hereinafteix v Another oh'ect of my invention is the pro- The latch head 12 has bevelled portions 16 vision of a sliding latch lock wherein the and 17, the bevelled portions 17 correspondopening through the face of the lock is so ing with the inclined side walls of the open- 20 arranged and the latch bolt so constructed ing 15 whereby to properly guide the latch as to permit the face plate to be interchanghead 12 in its movement lengthwise of the ing without interfering with the operation opening. A latch head 12 is likewise proof the latch bolt. vided with bevelled surface portions 16' and lVith the above and other objects in view, 17 corresponding with the inclined side 25 the invention consists in the novel features walls of the opening 19.

In Fig. 4. it will be Fig. 5 is a detail transverse section on the noted that the plate 18 is provided with an line 5-5 of Fig. 4, extension 20 having a shallow recess 21 40 Fig. 6 is a detail. elevation illustrating a therein thelower edge is inclined as at 22. slightly modified form of latching bolt. From this construction it will be apparent In carrying out my invention the usual that when the door is closed the tapering body me b 1 Of a ock is provided and face of the latch head 12 will engage within I which includes the sliding latch member 2 the recess21, the lower edge of the latch 15 with the diverging arms 3 arranged upon head riding upwardly upon theincline 22 opposite sides of the actuating spindle 4 to until the latch head is forced into the openwhich the usual knobs are attached. The ing 19 through the tension of the spring construction illustrated includes the lugs5 13. One of the bevelled portions 16' on the attached to the bolt 4 and engaging outlatch head will then engage the wall of the 50 turned ends 6 of the latch member 2. The opening 19 which forms a stop shoulder beforward edge of the body 1 is manually neath the inner end of the bevelled por opened but in the present instance is closed tion 22. i by a detachable face plate 7 which is at- As will be evident from the description tached to the ears 8 on the body 1 by means herein the latch bolt is adapted for engage- 55 of the screws 9. Arranged within the body 1 ment with the inclined surface 22 and upon adjacent the upper face thereof is a guide engagement therewith adapted to ride upwardly thereupon to a point where the latch bolt head is disposed in the opening 19, by the action of the spring member 13, with the bevelled surfaces 16 and 17 thereof, engaging the adjacent inclined side walls of this opening. As the opening 19 is disposed at an oblique angle with respect to the opening 15 it is manifest that when the latch bolt head is in engagement in the opening as above stated, any vibration of the door, on its hinges, will cause the latch bolt head to settle downwar lly in its engaged position in the openings 15 and 19 and be wedged therein thus preventing self-displacement of the latch bolt head from engaged position, thereby accomplishing one of the many objects of the invention.

In Fig. 6 I have illustrated a slightly modified form of latch member wherein the stem of the latch member is provided with an enlarged portion 23 having inclined opposed faces 24: which are engaged by the pin 25 carried byvthe casing of the lock for raising the latch head 12 upon its closing movement thus permitting the latch head to be sprung into the opening 19 of the locking plate 18 and thence dropped clownwardly into a secure latching position.

It will be apparent that the plate 17 may be readily reversed and the latch member operated in the same manner as set forth above.

While I have shown and described the preferred embodiment of my invention, it A will be understood that various changes and alterations maybe made without departing from the spirit of the invention or the scopeof the appended claims.

Havingthus described my invention, what I claim is: V

1. A look member including a spring pressed latch bolt, a lock body, a detachable plate upon one side of the body having an opening therethro-ugh disposed at an oblique angle with respect to the plate, a

head on the latch bolt, bevelled surfaces on the head for engaging the walls of the in clined opening and means whereby to actuate said latching boltas for thepurposes set forth.
